51. OneSim VoIP

    • How does OneSim VoIP work when the call is received?

      When someone dials your OneSim VoIP enabled Personal Extra Number (PEN), the system will first check if your OneSimCard phone is registered with the OneSim VoIP app on a Wi-Fi network. If it is registered, the call will be sent using VoIP. If the OneSim VoIP app is not running or it is not registered on a Wi-Fi network, then the call will be sent using the standard OneSimCard roaming network and charged our standard roaming rates.

    • Why can't I receive phone calls and SMS on my Android phone when the screen is off?

      Newer Android OS versions have settings that do not allow apps to run in the background by default. This means that you will get an SMS or a phone call only while your phone display is ON. Once the  phone goes to sleep, the app will get deactivated.

      To fix this, you need to make a change in your phone's battery optimization settings:

      Settings -> Apps and notifications -> See All Apps -> 1SimVoIP -> Advanced -> Battery -> Don't Optimize

      The settings path may slightly differ depending on the phone model, but usually it is located in the  App's Battery menu.

      Yes. All unlocked iPhones' Hotspot feature works with OneSimCard SIM.

       
      There are a few settings to make sure for this to function properly on your iPhone:
      1. Settings - Cellular - Cellular Data - ON
      2. Settings - Cellular - Data Roaming - ON
      3. Settings - Cellular - Cellular Data Network - Cellular Data - APN = APN will be set automatically

60. Troubleshooting Questions

    • I have a OneSimCard SIM and my phone will not register on a roaming network, what's wrong?

      Sometimes when moving from the USA, Canada or Mexico to another country, the SIM card will need to be reset to properly register on a new country roaming network.

      • If you have the OneSimCard Menu on your phone (it may be called Sim Application Menu on iPhones or SIM Toolkit on Androids), go to the menu, scroll down to Settings and enter Service Code 2003 and confirm, then Code 000 and confirm. For older SIM cards after this enter Service Code 1101 and confirm. Turn the phone off and then back on. 

      • If you do not have access to the OneSimCard Menu then turn off your phone, remove the battery for 20 seconds, reinstall the battery and then turn back on your phone.
